Hi, I have the same probleme, The Autoit script work but it still ask me the serial. My serial work and is in the Abcpy.ini. When i launch the msi file without autoit it dont find my serial in Abcpy.ini ! I don't understand. My Abcpy.ini look like : [OEM Install] USERNAME=Bluberry COMPANYNAME=Home SERIALNUMBER=XXXX-XXXX-XXXX-XXXX-XXXX-XXXX Is this possible to enter the serial with autoit ? and how ? Thanks, You're great
